This is the female rose breasted grosbeak - had to look that one up - sure looks different than her mate. I've seen the male once or twice - but never quick enough to catch him.
I had one stop by my feeder last week and I was hoping to see the male but he never showed. They are not common here so I was really pleased that I got a shot of her. I don't know if I'll post it as it's not as nice as this one, but I was still happy I caught her. Good shot!
